How do you cut t-nuts/slotted nuts with a router table?

Y want to use finger joints with T slotted captive nuts like this http://www.instructables.com/id/How-to-Build-your-Everything-Really-Really-Fast/step4/The-T-nut-Crossed-T-nut-Jesus-Nut-Slotted-Insert-N/

I only have hand tools and a mini router table.

¿Is it possible? ¿Is there any other convenient joint I can use in Acrylic with just this tools? (with screws, I don't want to use glue)
